“…Data presented in Table (3 A) clearly showed that the mineral NPK rates did not significantly affect the bulbing ratio (%) in both seasons. Similar results were reported by Miah et al, (2005); Islam et al, (2007); Kandil et al, (2013-a); and Mohamed et al, (2019) who found that foliar spraying with calcium and potassium compounds individually and/or mixing together decreased the number of days to maturity as compared to 100% NPK alone. Concerning injection rates with nano NPK, data illustrated in (Table 3 A) revealed that injection rates with nano NPK significantly affected bulbing ratio only in the second season.…”

This experiment was carried out at the Experimental Farm of Shandaweel Agricultural Research Station, Sohag, (ARC), during 2018/2019 and 2019/2020 seasons, to study the effect of nano fertilizers through injection on growth, yield and quality of onion Giza 6 Mohassan cultivar under Sohag conditions. Four different mineral (NPK) treatments (100% NPK, 75% NPK, 50% NPK and 25% NPK) and four different injections with nano NPK [(control (treatment without injection), 5, 10, and 15 L fed. -1 in addation to the control treatment (without injection) were applied. The experiment was conducted in split plot design with three replicates. The different mineral NPK treatments were arranged in the main plot and the different injection with nano NPK treatments were assigned to sub plots. The results showed that both of the mineral NPK rates and the injection onion with nano NPK rates significantly affected most of studied traits, in the both seasons. The interaction between the two studied factors, significantly affected both total and exportable bulb yield traits in two seasons. The injection with the nano NPK rate (10 L fed. -1 ) and the mineral NPK (75% NPK and 100% NPK) achieved the highest values of total bulb yield (21.99 and 21.85) ton fed. -1 . in the first and second season, respectively. While, the treatment without injection (control treatment) with the lowest mineral NPK (25% NPK) gave the lowest values of total bulb yield (14.06 and 12.75) ton fed.in the first and second season, respectively. The injection with the nano NPK rate (15 L fed. -1 and 10 L fed. -1 ) achieved the highest values of exportable bulb yield (18.51 and 18.56) ton fed. -1 in the first and second season, respectively. Therefore, the results of this study recommend the use of mineral NPK combined with nano NPK as soil injection (75% mineral NPK + 10L fed. -1 nano NPK), to increase the total and exportale yield of onion, reduce environmental pollution by providing a quarter of the recommended amount of chemical fertilizers and saving hard currency by reducing the import of chemical fertilizers.

“…Hal tersebut menunjukkan bahwa semakin besarnya ukuran bahan tanam dengan jarak tanam yang optimum mampu menghasilkan pertumbuhan dan berat kering tanaman yang optimum. Hal tersebut disebabkan karena laju fotosintesis meningkat sehingga menghasilkan fotosintat yang lebih banyak dan laju fotosintesis dapat dipengaruhi oleh jumlah daun dan bobot kering tanaman (Mohamed et al, 2019). Hasil panen bawang putih berkurang dengan semakin kecil ukuran siung dengan semakin lebarnya jarak tanam (Tabel 3).…”

<p class="Abstract">The effort to increase garlic productivity through improvement of cultivation technology. This study aimed to determine the proper size of cloves and planting distance thus resulting in the best growth and yield of garlic var. Lumbu Hijau. This study was conducted in April-September 2018 in Horticulture Seed Garden Tawangmangu, Karanganyar. This method used was Randomized Complete Block Design (RCBD) factorial with 2 factors, namely clove size (large, medium, and small) and planting distance (10 cm x 10 cm, 12.5 cm x 12.5 cm, 10 cm x 15 cm). The result showed that the size of cloves had significant effect on plant height, number of leaves, plant dry weight and yield. Planting distance had significant effect on yield. The use of large sized cloves (diameter 19-35 mm) increased plant height, number of leaves, plant dry weight and yield of garlic var. Lumbu Hijau. Maximum garlic yields on spacing of 10 cm x 10 cm. The combination of the size of the cloves with spacing affected plant height, plant weight and the yield of garlic. The greater the size of the cloves with the wider planting distance causing higher plants. The smaller the size of the cloves with a wider spacing causing low garlic yield.</p>
